背景:近年来,国家预警评分2(NEWS2)用于早期预测,患者临床状况的恶化。到目前为止,国家预警评分(NEWS2)的预测准确性,修订创伤评分(RTS),与创伤和创伤严重程度评分(TRISS)有关的创伤患者死亡率尚未进行比较。因此,这项研究的目的是比较NEWS2,TRISS,基于院前数据集的RTS预测创伤患者死亡率。
方法:这项横断面回顾性诊断研究对6905名创伤患者进行,其中4191人被认定合格,指的是伊朗南部最大的创伤中心,设拉子,在2022-2023年期间,根据他们的院前数据集,以比较NEWS2、RTS、和TRISS在预测住院死亡率方面的作用。患者分为死亡组和存活组。人口统计数据,生命体征,从患者中获得GCS,并计算并比较两组之间的评分系统。TRISS和ISS是使用院内数据集计算的;其他则基于院前数据集。
结果:共有129名患者死亡。年龄,受伤原因,住院时间,SBP,RR,HR,温度,SpO2和GCS与死亡率相关(p值<0.001)。TRISS和RTS的敏感性和特异性最高(77.52,CI95%[69.3-84.4]和93.99,CI95%[93.2-94.7])。TRISS的ROC曲线下面积最高(0.934),其次是NEWS2(0.879),GCS(0.815),RTS(0.812),国际空间站(0.774)。TRISS和新闻优于RTS,GCS,和ISS(p值<0.0001)。
结论:这项新颖的研究比较了NEWS2,TRISS,基于院前数据预测死亡率的RTS评分系统。研究结果表明,所有的评分系统都可以预测死亡率,TRISS是其中最准确的,其次是NEWS2。考虑到时间消耗和易用性,根据院前数据集,NEWS2在预测死亡率方面似乎是准确和快速的。
BACKGROUND: In the recent years, National Early Warning Score2 (NEWS2) is utilized to predict early on, the worsening of clinical status in patients. To this date the predictive accuracy of National Early Warning Score (NEWS2), Revised Trauma Score (RTS), and Trauma and injury severity score (TRISS) regarding the trauma patients\' mortality rate have not been compared. Therefore, the objective of this study is comparing NEWS2, TRISS, and RTS in predicting mortality rate in trauma patients based on prehospital data set.
METHODS: This cross-sectional retrospective diagnostic study performed on 6905 trauma patients, of which 4191 were found eligible, referred to the largest trauma center in southern Iran, Shiraz, during 2022-2023 based on their prehospital data set in order to compare the prognostic power of NEWS2, RTS, and TRISS in predicting in-hospital mortality rate. Patients are divided into deceased and survived groups. Demographic data, vital signs, and GCS were obtained from the patients and scoring systems were calculated and compared between the two groups. TRISS and ISS are calculated with in-hospital data set; others are based on prehospital data set.
RESULTS: A total of 129 patients have deceased. Age, cause of injury, length of hospital stay, SBP, RR, HR, temperature, SpO2, and GCS were associated with mortality (p-value < 0.001). TRISS and RTS had the highest sensitivity and specificity respectively (77.52, CI 95% [69.3-84.4] and 93.99, CI 95% [93.2-94.7]). TRISS had the highest area under the ROC curve (0.934) followed by NEWS2 (0.879), GCS (0.815), RTS (0.812), and ISS (0.774). TRISS and NEWS were superior to RTS, GCS, and ISS (p-value < 0.0001).
CONCLUSIONS: This novel study compares the accuracy of NEWS2, TRISS, and RTS scoring systems in predicting mortality rate based on prehospital data. The findings suggest that all the scoring systems can predict mortality, with TRISS being the most accurate of them, followed by NEWS2. Considering the time consumption and ease of use, NEWS2 seems to be accurate and quick in predicting mortality based on prehospital data set.
